A recent Mac OSX Sierra upgrade killed my MAMP!

This is actually an easy fix.  Just trash your MySQL log files.  Navigate to:

/Applications/MAMP/db/mysql{xx}/ and delete the 2 log files here.  (Don’t worry.  MySQL will rebuild them.)

They are the files labelled ib_logfile{X}

Just move those to the trash and restart MAMP!
